JD1A(B) type electromagnetic speed control motor control deviceDetailed product description：

The JD1A (B) type electromagnetic speed regulating motor control device is an energy-saving product jointly promoted by the country. Used to control the speed of electromagnetic speed regulating motors, achieving stepless speed regulation without constant torque. When the load is a fan or pump, it has a significant energy-saving effect. Widely used in various industrial automation production lines such as machinery, metallurgy, power generation, papermaking, printing, cement, tobacco, cables, etc.
